In the early hours of Sunday morning,
another shooting took place in Dayton, Ohio. Police have stated that nine people, as well as the suspected shooter, died in the incident. Local police were reportedly on duty nearby and responded “in a very short period of time,” said Dayton Police Lt. Col. Matt Carper.

In June, five people were injured and 12 died at a
shooting in Virginia Beach, Virginia, the deadliest mass shooting so far this year. The shooter died after a gunfight with police.

And last month, at the most recent high-profile mass shooting this year, which took place at the Gilroy Garlic Festival in California, three people died and 12 others were injured. The local coroner’s office recently stated that the shooter
killed himself.

In the case of both the El Paso shooting and the Gilroy Garlic Festival, there were early reports of multiple shooters, which is rare. Gilroy Police Chief Scot Smithee
later said it was likely there was no second shooter.

However, one recent exception to the rule that there’s rarely a second shooter was
the May shooting at the STEM School in Highlands Ranch, Colorado, where two shooters were apprehended by police.

Last year, the FBI released a report on the perpetrators of active shootings from 2000 to 2013. The FBI’s research revealed many of the common ideas associated with active shooters
are misconceptions.

In the last few years there have been two mass shootings in Texas that have attracted national attention: In November 2017, 26 people were killed in a shooting at a church in Sutherland Springs, Texas, and in May 2018, 10 people were killed at a high school in Santa Fe, Texas.
